You will conduct a study of 100 people with cancer to better understand people's view the role of nutrition in their cancer diagnosis and treatment.

Her patients tend to fall into three categories: “Like a lot”, “like somewhat”, and “dislike a lot”. She believes that she might get different satisfaction scores from people in each group, but (because she's not great at numbers) she wants you to do an ANOVA to be sure. She has collected data from 12 patients (three equal groups) with the following results.     Group 1) “Like a lot”               Mean:   8                    SS: 2   N:                      df:            Group 2) “Like somewhat”     Mean:   5                    SS: 6   N:                      df:             Group 3) “Dislike a lot”         Mean:    2                   SS: 4   N:                      df:              Grand Mean:      4    df Within-Group: 9  df Between-Groups: 2    Estimated Variance (S21) for Group 1: _______ Estimated Variance (S22)…

There are 9 million enrollees in the Department of Veterans Affairs health care system. It wants doctors and nurses to treat pain as a “fifth vital sign” to be recorded along with blood pressure, pulse, temperature, and breathing rate. If you were to aid the VA in this situation, how would you measure a patient’s pain? How could this “fifth vital sign” be a potentially invalid measure? Answer each question with at least one paragraph of three complete sentences.

Ms Best is a high school math teacher. Ms. Best has two sections of geometry. She teaches one section using a traditional approach. The second section Ms Best uses a tasked-based learning approach. The table below summarizes the descriptive statistics for the final exam. Ms Best concludes that the tasked-based learning approach students consistently scored higher than the traditional students.
